Not sure if this is the correct forum; please excuse if not. I've been looking to calculate pi as a burn-in / benchmark on some newer systems, both in Windows and MS-DOS. It seems many of these old programs have gone into oblivion, especially the best ones. I referenced Stu's pi page and Pifast v. 4.4, directed from the wikipedia article:

http://members.shaw.ca/francislyster/pi/supercomputer.html

But it is an obsolete / not found page, even though Wikipedia claims that v. 4.4 may be found there. And there is no extant waybackmachine cached page or binary of version 4.4, either!

Does anyone have a working binary of PiFast version 4.4 for Windows?

Further, there is:
https://thestarman.pcministry.com/math/pi/piprogs.html

which does have piFast v 4.3, which I found on my hard drives from years ago. Version 4.4 is faster, it was claimed.

Finally for MS-DOS, there is Pi-AGM, from Carey Bloodworth:

The download link is not preserved for the latest version, 2.31:
Cbpi231b.zip at Wayback, either, although the source code file cbpi231s.zip is there. I was unsuccessful in building it from source on DJGPP in DOS.

So, as my Google-Fu is not up to par, and has been unsuccessful in locating either pifast44.zip or cbpi231b.zip, I appeal to the fine folks in the forum for some help. Does anyone out there have either of these two programs preserved (ie, their last and final versions)?

Many thanks for any help. These have "disappeared" into oblivion, as seems to be happening so much with legacy software these days. There was a *single* link which wasn't mirrored / backed up anywhere, once it goes, the programs go...
